The present study examines the effect of reversed-phase high-performance liquid chromatography (RP-HPLC) column diameter (1mm to 9.4mm I.D.) on the one-step slow gradient preparative purification of a 26-residue synthetic antimicrobial peptide. When taken together, the semi-preparative column (9.4mm I.D.) provided the highest yields of purified product (an average of 90.7% recovery from hydrophilic and hydrophobic impurities) over a wide range of sample load (0.75-200mg). Columns with smaller diameters, such as narrowbore columns (150x2.1mm I.D.) and microbore columns (150x1.0mm I.D.), can be employed to purify peptides with reasonable recovery of purified product but the range of the crude peptide that can be applied to the column is limited. In addition, the smaller diameter columns require more extensive fraction analysis to locate the fractions of pure product than the larger diameter column with the same load. Our results show the excellent potential of the one-step slow gradient preparative protocol as a universal method for purification of synthetic peptides.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule.
